SPECIFICATION frming part of Letters Patent No. saoenuateaDecember1s,1ee4. lippncfnion met 'March 16, v1894.. serai No. 503,856.(No mais) To all whom it may concern,.-

Be it known that I, DAVID YOUNG GRIEB, a citizen of the United States ofAmerica, residing at Suburba, in the county of Hamilton and State ofTennessee, have invented a new and useful Improvementin Hand- Trucks, ofwhich the following is av specification.

The hand-trucks in use, may be briefly described as consisting of twowooden bars, braced together, and provided at one extremity with a noseor lip, the otherextremities terminating in handles. On this frame, nearthe end carrying the nose, are mounted axle boxes in which the runninggear is carried. Among the objections to this form are, liability ofbreaking the frame on account of unequal distribution of the load, lossof time in repairing if any part be injured, expense of supplying newpieces, and the difficulty in putting them in place without whollydismantling the truck.

The object of my invention is to overcome these difficulties, and itconsists in so constructing tlie-V truck that the load will be equallydistributed, that if a part is injured it can be replaced withoutdismantling the structure, and in the combination and arrangement ofparts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation; Fig. 2, a top plan; Fig.3, avertical section on line 3-3 of Fig. 1; Fig. 4, a section on line 44 of Fig. 1.

The frame is constructed on the truss system. Each side of the frameconsists of an upper bar, a, a lower bar, b, and an intermediate bar, c,bent in a series of Vs.

Theintermediate bar is secured alternately to the upper and lower barsexcept at points near the ends where the three are bolted together.Bolts, d, taking through ferrules, d', connect the bars and brace-rodsat the points of the V, the ferrule serving to maintain the properdistance between the upper and lower bars. The brace-.iron being bentand secured in this manner` the opposite sides of the Vs brace inopposition so that a load applied to any part is equally distributed.The lower bars, b, are bent at b to form hangers for-the boxes, lo, ofthe running gear and are exten ded upwardly beyond the end of the upperbars a to afford supports for a nose iron, n, consisting of a plate ofangular shape extending from side to side of the truck, one part n',being secured between the upper bar, a, the bracerod, c, and the lowerbar,b,-thus affording a brace between the sides of the truck as welll asaffording a rigid support for the nose. The handles preferably consistof a hollow hand piece, e, driven or shrunk on a bar, f, bolted betweenthe upper bar, a, and the lower bar, b. In the forni shown the bar, f,isrectangularand the hand pieces circular in cross section and theintervening spaces are filled with a plastic material w, thus making apractically solid handle.

T-he legs consist of braces, g, and V shaped angle irons, h. The boxes,7o, are each provided with a groove k and are held in position by abolt, l, taking through the two sides of the hangers formed by the bendin the lower bar, b, and resting in the groove. By this lconstructionthe bolt, Z, receives the pressure from the load and transmits it to thebox, the pressure from the sides of the hanger y being inward and upwardagainst the box,

.while the Abolt serves as a pivotl and centering device thus permittingthe box to adjust itself to the line of the axle.

The sides of the frame are connected by brace irons, g, having thecontinuous V- shape as the intermediate bar, c, and these are connectedby plates, s, extending lengthwise of the truck. f

The parts may all bemade from templets and any part may be replaced byorders at small cost. Each part is held in place by its own bolts andcan be easily removed and replaced by an unskilled workman. The wholecan be shipped in knock down form and the parts can be assembled by anyperson know- 'ing how to use a wrench.

2. A frame for a truck consisting of aplu- IOO rality of upper and lowerbars; a V-shaped brace iron connecting each pair of upper and lowerbars, bends in the lower bars adapted to form hangers for the boxes; atransverse groove in each of the boxes; bolts taking through the hangersand resting in the grooves, and brace-irons oonnectin g the pairs,substantially as and for the purpose specified 3. The combination in atruck of upper bars a, and lower bars b having bends b brace irons, c,between the upper and lower bars, cross brace irons, g, connecting thesides of the frame, bolts cl and ferrules d', connecting and bracing thebars and brace irons;

boxes 7c, having groove 7o', and bolts Z oonnecting the sides of bend band resting in the groove k', substantially as and for the purposespecified. f
